Try to run it in ghci, step by step:

1) input<-getContents

better to replace this step by a

1) input <- readFile "mytestdata"


2) let w@(nstr:locPairStrs) = lines input
3) let n = read nstr::Integer
4) let locs = take (fromIntegral n) $ map (tuplify2 . (\x-> map
stringToRatio $ words x))
                     locPairStrs
5) let answer = solve n locs
6) putStrLn $ " n : "++ show n
7) putStrLn $ " locs : "++show locs
8) putStrLn $ show $ vornoiGraph locs
9) putStrLn $ plotAsString locs answer

see what happens, and where.
